Descripción

General description

GRINCH (Glucose-Responsive Insulin-secreting C-peptide modified Human proinsulin) is a rat insulinoma cell line derived from the INS-1 cell line. INS-1 cells were transfected with the hPro-CpepSfGFP construct containing the human insulin sequence with a C-peptide modified with a C-terminal superfolder GFP insert. The GRINCH cell line exhibits efficient glucose-stimulated insulin secretion, making it a good model to study insulin secretion regulation and pancreatic β-cell function. The fluorescent C-peptide is co-stored and co-secreted with human insulin, allowing the tracking and quantification of insulin biosynthesis in real time.

GRINCH cells express human insulin with a C-peptide GFP tag?.

Application

• Each vial contains > 1 X10⁶ viable cells.
• Cells are tested negative for infectious diseases by Essential CLEAR Panel by Charles River Animal Diagnostic Services.
• Cells are verified to be of rat origin and negative for interspecies contamination from human, mouse, Chinese hamster, Golden Syrian hamster, and nonhuman primate (NHP) as assessed by a Contamination Clear panel by Charles River Animal Diagnostic Services
• Cells are negative for mycoplasma contamination.

Features and Benefits

SCC611, the GRINCH rat insulinoma cell line, is a pancreatic beta cell line transfected with the hPro-CpepSfGFP construct containing the human insulin sequence.

Target description

Approximately 1 in 11 adults globally has diabetes, leading to 12% of health expenditure being diabetes- related. Diabetes mellitus refers to a group of metabolic diseases involving chronic hyperglycemia due to reduced insulin secretion, insulin synthesis, or increased insulin resistance.

Recent advancements in technology have enabled the molecular understanding of diabetes in childhood and in non-obese patients, unveiling the role of single gene defects. These defects, found in genes encoding beta-cell components like potassium channels, glucokinase, transcription factors, and insulin, contribute to 1-5% of all diabetes cases and are characteristic of monogenic diabetes. Insulin gene mutations can lead to various diabetes subtypes by affecting insulin folding, causing retention in the endoplasmic reticulum (ER), triggering ER stress, beta-cell death, and impairing insulin-insulin receptor (IR) interaction.

Source

The GRINCH cell line was derived from INS-1 cells. The INS-1 cell line was derived from x-ray induced insulinoma in rats.
